Double Cleansing
Double cleansing is the practice of washing the face twice, first with an oil-based product and then with a water-based one. It is treated as a foundational first step in many Korean skincare routines.
The two steps
The first step uses an oil-based cleanser, such as a cleansing oil or balm, to dissolve oil-soluble substances like makeup, sunscreen, and sebum. The second step uses a water-based cleanser, typically a foaming or gel wash, to remove water-soluble debris, sweat, and any residue left behind. Together they aim for a thorough clean without relying on a single harsh product.
How it works
The method rests on the simple chemistry that oil dissolves oil. Many sunscreens and long-wearing makeup products are water-resistant and difficult to remove with a water-based cleanser alone, so an oil cleanser lifts them more effectively first. The water-based follow-up then clears the remaining film. The goal is clean, comfortable skin rather than the tight, stripped feeling that can come from over-washing.
Context and cautions
Double cleansing is especially associated with people who wear sunscreen daily and heavier makeup, both common in Korean routines. It is best understood as a popularized practice rather than a single inventor's creation. It is not mandatory for everyone, and dermatologists often note that those with very dry or sensitive skin should adjust frequency and product choice to avoid irritation.

What is double cleansing?
Double cleansing is a two-step Korean method: first an oil-based cleanser dissolves makeup, sunscreen and sebum, then a water-based cleanser removes sweat and water-soluble debris. The pairing aims to clean thoroughly without the tightness or stripping that one harsh wash can cause.
Do I really need to double cleanse?
At night, if you wear sunscreen or makeup — yes. Water-based cleansers cannot break down water-resistant sunscreen, so a single cleanse leaves a film behind. In the morning, one gentle cleanse or just water is plenty.
